Here's an example of the inside of a small school bus
that we wired in 8 LEDs (4 yellow & 4 red) and connected to one of our effects
simulators to generate the alternating flashing lights changing from yellow to
red as is typical for this vehicle type.

We used 5 sections of our N8106 mounting boards to hold
3 resistors and allow for multiple wire connections inside the bus. That let us
easily connect all of the 16 wires from the LEDs and the connections to the
simulator, and made mounting simple with the double-backed Kapton tape on the
back of the boards. Spaghetti sauce anyone?
